This little speaker is a talking point wherever it goes. It’s a party in a box, and a buskers dream. Perfect for little informal gatherings, where people are drinking, this can play MP3s, and have two musicians jamming through this at the same time. A singer and a guitarist over backing tracks, or a singer and a bassist, with maybe an aqoustic guitarist not going through this, at a barbecue?, would work perfectly. It’s battery lasts a good 10 hours odd, and has ‘loads’ of volume, and I mean all you want and then plenty. I’d happily use this for a proper full party sound system, just on its own, and using just battery, no problem at all. Maybe bring a small speaker stand?, that’s all. It only plays MP3 music format though, unless you plug your phone into it, and play m tracks that way, it easily takes the lead. Love this thing to bits, it’s a little party machine, and can pack a whallop if needed.
